Tendon reflex (or T-reflex) may refer to:

A stretch reflex, when the stretch is created by a blow upon a muscle tendon. This is the usual definition of the term. ^[1]^[2] A common example is the standard knee-jerk response when visiting the doctor. ^[3] Deep tendon reflex also usually refers to this sense. A deep tendon reflex is often associated with muscle stretching. ^[4] Tendon reflex tests are used to determine the integrity of the spinal cord and peripheral nervous system, and they can be used to detect the presence of a neuromuscular disease. ^[5]
The Golgi tendon reflex, motivated by that the sensory receptors for this reflex are anatomically located in the tendon, while the sensory receptors for the stretch reflex are actually inside the proper muscle.

Testing[edit source | edit]

To test the reflex,tap on the tendon. In a healthy individual the intensity on both sides is equal. This means that the connections between the spinal cord and the muscles are undamaged. ^[6]

Functions of Tendon Reflex[edit source | edit]

The tendon reflex is a response to extensive tension on a tendon.^[7]It helps avoid strong muscle contractions which could tear the tendon from either the muscle or bone.^[8] In sports, quick movements can damage the tendon before the reflex can occur. .^[9]The tendon reflex also helps spread the workload more evenly over the entire muscle by preventing “muscle fibers connected with overstiumlated tendon organs so that their contraction is more comparable to the contraction of the rest of the muscle.”^[10]

Abnormal blink reflex recovery cycle in manifesting and nonmanifesting carriers of the DYT1 gene mutation.

Fong PY1, Edwards MJ, Lu CS, Chen RS, Rothwell JC, Bhatia KP, Huang YZ.
Neuroreport.Neuroreport.2016 Sep 28;27(14):1046-9. doi: 10.1097/WNR.0000000000000653.
The aim of this study is to evaluate the brainstem function in DYT1 carriers manifesting clinical dystonia (MDYT1) and those without clinical symptoms (NMDYT1). Motor cortical inhibition and plasticity were found to be abnormal in MDYT1, whereas these were less abnormal in NMDYT1. However, the spina

Supraspinal control of spinal reflex responses to body bending during different behaviours in lampreys.

The Journal of physiology.J Physiol.2016 Sep 2. doi: 10.1113/JP272714. [Epub ahead of print]
Spinal reflexes can be modified during different motor behaviours. However, our knowledge about the neuronal mechanisms underlying these modifications in vertebrates is scarce. In the lamprey, a lower vertebrate, body bending causes activation of intraspinal stretch receptor neurons (SRNs) resulting
